Abstract: To overcome the color distortion and computational time-consuming problems with traditional RGB color space model, this paper proposes a method based on YUV color space model for creating High Dynamic Range(HDR) color images. This method uses a series of digital images with different exposure to generate a HDR color image. Experimental results show that the method is more efficient in computational speed and has better color image quality in comparison.

Key words: High Dynamic Range(HDR), camera response function, HDR display, YUV space, color image composition, multi-exposure
